Relative global adjustments for a full album

[Hello.Henning]

Hi. Sometimes it happens to me that I edit photos and at the end, I notice that all of them are slightly too dark or slightly too warm. While I realize that I can copy settings from one photo and paste them on other photos, this would change parameters to the same absolute value. I also had a look at the workflows but couldn't find anything. What I would like to be able to do is, for example, add 3 percent to the temperature setting of each photo, without having to manually adjust each photo again. Is there an elegant way to do this? Thanks!
